Eric Yang updated YARN-9499:
----------------------------
Parent Issue: YARN-10078 (was: YARN-9414)
> Support application catalog high availability
> ---------------------------------------------
>
> Key: YARN-9499
> URL: https://issues.apache.org/jira/browse/YARN-9499
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Eric Yang
> Priority: Major
>
> Application catalog is mostly a stateless web application. It depends on
> backend services to store states. At this time, Solr is a single instance
> server running in the same application catalog container. It is possible to
> externalize application catalog data to Solr Cloud to remove the single
> instance Solr server. This improves high availability of application catalog.
> This task is to focus on how to configure connection to external Solr cloud
> for application catalog container.
